Carbon fiber gear seal for artificial intelligence robots and its manufacturing method

Abstract

A carbon fiber gear seal for artificial intelligence robots comprises at least two carbon fiber substrates, each of which is formed by a plurality of randomly distributed fibers to create a discontinuous fiber structure. The carbon fiber sheet is made from recycled carbon fiber material. After the at least two carbon fiber substrates are stacked, the adhesive layer between two adjacent carbon fiber substrates is used to bond the two stacked carbon fiber substrates together. The carbon fiber substrates are manufactured using a non-woven process, resulting in a high-strength, tough, uniform, and durable carbon fiber gear seal for artificial intelligence robots.
